This seems like a good place for a fluorescence question: If a pink spinel has faint red fluorescence, would it be noticeable in bright sunlight?

I found a pair of what I believe are Sri Lankan hairpins with pink sapphires/rubies set in gilt silver, from c. 1900. The stones fluoresce a beautiful red. (Here I'm shining the blacklight on one of the hairpins in a dim but not dark room. The shots I took in the complete dark came out really blurry.)
